Problems solved by technology
When the battery is over-discharged or misused, a large amount of gas will be generated. A large amount of gas may cause the battery to leak or even explode.
In order to solve the potential safety hazard of battery explosion, the safety factor value of the comparison between the battery sealing strength and the rupture strength of the sealing ring safety valve was considered when designing the battery. The safety factor value of the LR6 battery is 1.3, and the safety factor value of the LR03 battery is 1.5. After completion, how to truly reflect the sealing strength of the battery is a technical problem existing in the prior art

The invention discloses a dry battery sealing strength testing system for solving the problem that the sealing strength of an existing dry battery cannot be tested. The dry battery sealing strength testing system comprises a compressed air generation device, a battery perforating device, battery sealing strength detection fixtures, a gas-liquid conversion device, a hydraulic water conveying pipeline, a perforated compressed air conveying pipeline and a tested compressed air conveying pipeline; the battery perforating device is connected with the compressed air generation device by the perforated compressed air conveying pipeline; the gas-liquid conversion device is connected with the compressed air generation device by the tested compressed air conveying pipeline; the tested compressed airconveying pipeline is provided with an air regulating valve; the gas-liquid conversion device is connected with a water storage device by a water pipe and is connected with the battery sealing strength detection fixtures by the hydraulic water conveying pipeline; and the hydraulic water conveying pipeline is provided with a flowmeter. By using the dry battery sealing strength testing system, thesealing strength value of a produced battery can be monitored, so that the effect that the sealing strength value of the battery is within an explosive safety coefficient range can be ensured, and furthermore, the battery has no potential safety hazards.
Description
technical field [0001] The invention relates to a test system, more specifically to a dry battery seal strength test system. Background technique [0002] With the diversification of electrical appliances, dry batteries have become a necessity in people's lives. At the same time, people have put forward higher requirements for the battery's anti-leakage performance and anti-explosion safety performance indicators, especially when the battery is over-discharged and the battery is misused. Battery safety features. When the battery is over-discharged or misused, a large amount of gas will be generated. A large amount of gas may cause the battery to leak or even explode. In order to solve the potential safety hazard of battery explosion, the safety factor value of the comparison between the battery sealing strength and the rupture strength of the sealing ring safety valve was considered in the battery design. The safety factor value of LR6 battery is 1.3, and the safety factor ...
